68.Sh DESCRIPTION
69These interfaces may be used to look up information from the
70.Xr audit_event 5
71database, which describes audit events.
72Entries in the database are described by
73.Vt "struct au_event_ent"
74entries, which are returned by calls to
75.Fn getauevent ,
76.Fn getauevnam ,
77or
78.Fn getauevnum .
79It is also possible to look up an event number via a call to
80.Fn getauevnonam .
81.Pp
82The
83.Fn setauevent
84function
85resets the database access session for
86.Xr audit_event 5 ,
87so that the next call to
88.Fn getauevent
89will start with the first entry in the database.
90.Pp
91The
92.Fn endauevent
93function
94closes the
95.Xr audit_event 5
96database session.
97.Pp
98The
99.Fn getauevent
100function
101returns a reference to the next entry in the
102.Xr audit_event 5
103database.
104.Pp
105The
106.Fn getauevnam
107function
108returns a reference to the entry in the
109.Xr audit_event 5
110database with a name of
111.Fa name .
112.Pp
113.Fn getauevnum
114returns a reference to the entry in the
115.Xr audit_event 5
116database with an event number of
117.Fa event_number .
118.Pp
119The
120.Fn getauevnonam
121function
122returns a reference to an audit event number using the
123.Xr audit_event 5
124database.

147.Sh HISTORY
148The OpenBSM implementation was created by McAfee Research, the security
149division of McAfee Inc., under contract to Apple Computer, Inc., in 2004.
150It was subsequently adopted by the TrustedBSD Project as the foundation for
151the OpenBSM distribution.

154This software was created by
155.An Robert Watson ,
156.An Wayne Salamon ,
157and
158.An Suresh Krishnaswamy
159for McAfee Research, the security research division of McAfee,
160Inc., under contract to Apple Computer, Inc.
161.Pp
162The Basic Security Module (BSM) interface to audit records and audit event
163stream format were defined by Sun Microsystems.
164.Sh BUGS
165The
166.Va errno
167variable
168is not always properly set following a failure.
169.Pp
170These routines are thread-safe, but not re-entrant, so simultaneous or
171interleaved use of these functions will affect the iterator.
